Aliens Attack

Aliens Attack is a free alien shooter game online where waves of hostile extra-terrestrials descend on your position. This fast-paced arcade shooter fits perfectly into the alien game, alien shooter game, and UFO game categories while keeping the gameplay focused and intense. Your mission is simple but demanding: survive the swarm, eliminate every alien, and defeat the final boss to protect humanity.

Your objective is straightforward. Clear all incoming alien waves before they overwhelm you. You control a continuously firing weapon and must manage positioning, threat priority, and survival under constant pressure.

• Move using arrow keys, WASD, or swipe controls on mobile.

• Shoot by pressing the Spacebar, tapping, or clicking to fire continuously.

• Each stage ends with a powerful boss—observe its attack patterns and strike its weak points to win.

Aliens Attack rewards players who stay alert and adapt quickly as enemy waves grow stronger.

• Prioritise high-threat aliens first, especially fast or heavily armoured enemies.

• Stay mobile at all times; standing still leads to quick defeat.

• Continuous firing helps with crowd control, but accurate targeting clears waves faster.

• Watch enemy movement patterns to avoid being surrounded.
